Anonymous authentication for ejbs works on EAP 7.0.x using the following configuration:

<subsystem xmlns="urn:jboss:domain:remoting:4.0">
<endpoint/>
<http-connector name="http-remoting-connector" connector-ref="default" security-realm="ApplicationRealm">
<properties>
<property name="SASL_MECHANISMS" value="ANONYMOUS,PLAIN"/>
<property name="SASL_POLICY_NOANONYMOUS" value="false"/>
</properties>
</http-connector>
</subsystem>

Unfortunately, this same configuration does not work on 7.1.1. It looks
like the server still wants to use DIGEST-MD5 based authentication.

Has the legacy based configuration (non-elytron) for anonymous ejb
access changed on eap 7.1.1?

I am attaching the standalone.xml, server.log and client log.

Customer does not want to use elytron at the moment.
